Given numbers are 257, 400, 166, 479

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(257, 400) = 102800

GCD(257, 400) = ( 257 x 400 ) / 102800

= 257 / 400

= 257

Step2:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

Step3:

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

= 1 / 479

= 1

So, Greatest Common Divisor of 257, 400, 166, 479 is 1
